Antenatal Screening

The Wolfson Institute of Preventive Medicine, part of Barts and The London School of Medicine and Dentistry, is a leader in the field of antenatal screening for Down's syndrome.

The Antenatal Screening Service has been providing antenatal screening for Down's syndrome and open neural tube defects to women since 1989. We currently perform approximately 50,000 screening tests a year, making us one of the largest antenatal screening laboratories in the UK. Find out more about us.

Antenatal screening can identify pregnancies at high risk of abnormalities including Down’s syndrome; spina bifida, anencephaly and other open neural tube defects; and Edwards’ syndrome. Find out more about these congenital conditions.
